Nanoscale Thermal Imaging of Dislocation-Mediated Heat Transport
Ruilin Mao, Bingyao Liu, Jiaxin Liu +7
Dislocations in crystalline materials are widely exploited to tailor the thermal conductivity of semiconductors and thermoelectrics, yet a critical gap persists: direct measurement…
Atomic-scale mechanism of enhanced electron-phonon coupling at the interface of MgB thin film
Xiaowen Zhang, Tiequan Xu, Ruochen Shi +7
In this study, we explore the heterointerface of MgB film on SiC substrate at atomic scale using electron microscopy and spectroscopy. We detect ~1 nm MgO between MgB and S…
Atomic-scale observation of localized phonons at FeSe/SrTiO3 interface
Ruochen Sh, Qize Li, Xiaofeng Xu +11
In single unit-cell FeSe grown on SrTiO3, the superconductivity transition temperature features a significant enhancement. Local phonon modes at the interface associated with elect…
Phonon transition across an isotopic interface
Ning Li, Ruochen Shi, Yifei Li +13
Natural materials usually consist of isotopic mixtures, for which different isotopic ratios can lead to distinct material properties such as thermal conductivity and nucleation pro…
Single-dislocation phonons: atomic-scale measurement and their thermal properties
Yuehui Li, Bo Han, Xiaolong Yang +12
Nanoscale defects such as dislocations, have a significant impact on the phonon thermal transport properties in non-metallic materials. To unravel these effects, understanding of d…
